INCREDIBLE but true. Marketmen insist sales of the Akai colour TV, emperor of exchange offers, despot of discounts, slid from 49,000 sets in May to 33,000 in June to 30,500 in July. In the meantime, BPL has moved sales up from 52,000 in May to 56,000 in June to 81,000 in July. Of course, BPL has also cut prices, but nowhere near Akai levels. If you turn in your old 21-inch CTV, you can get a BPL 29-incher for Rs 24,000. An Akai one comes for Rs 7,000 less.
